Most cars would drag on EML, but that being BMW, that would harm their perceived higher reliability Yes, its importnat, and yes, it will cause the engine to run sub optimally

The sensor has no through passage so when connected correctly no harm will be done.

I guess the turbo seals, given some miles, may generate a samll amount of oil in the intake as well...

Possibly but not so likely on TD's as they have a much easier life than turbos on petrols

Funny you should say that - there's a 2.5TD on fleabay at the moment listed with a 'blown turbo' .. I have my doubts a about that and I'm almost tempted to take a punt on it for precisely the reason you say.

Bejeezus! Did you buy it already? If not, I have a used as-far-as-I-know-good one sitting in the toolbox that you're welcome to for the price of postage and a wee bit to cover a couple of drinks? (Took it off my old 2.5TD when I was playing find-the-fault-that-turned-out-to-be-the-autobox Grin

, it wasn't throwing any codes so I believe it to be a good sensor; they're electrically very reliable)

Given the entire state of the intakes on these TDs, I would hazard a guess that the majority of the oil in the TD intake has come from the turbo - would have thought if it was just blow by, is would hit a brick wall long before the turbo, but the oil starts just beynd air filter normally...
